Primary mucinous cystic neoplasms are rare tumours of the kidney, with a very few case reports in
the literature. They arise from metaplasia of renal pelvic urothelium. We describe here a 45-year-old
male who presented with pain in the abdomen and a lump in the left iliac fossa for two months.
Ultrasound and CT scan showed a large, complex, heterogenous mass in the central abdomen and
left iliac fossa, suggesting the possibility of dermoid cyst. Excision of the mass showed an enlarged
multicystic kidney fi lled with mucin, destruction of renal parenchyma and a small viable area of
grey white tumour. Histopathology revealed a peripherally located mucinous cystadenocarcinoma
arising in the background of chronic pyelonephritis and mucinous metaplasia. We report this case
for the rarity of the lesion and the associated clinical and radiological diagnostic dilemma.

Myofibroblastomas are soft-tissue neoplasms that are thought to arise from myofibroblasts. They are mostly observed in males 41–85 years of age; however, this lesion also occurs in women. The usual clinical presentation is a unilateral painless lump that is not adherent to overlying or underlying structures. Microscopically, myofibroblastomas can be divided into 5 subtypes: classical, epithelioid, collagenised, cellular, and infiltrative. Mammary ducts and lobules are absent in the typical histological subtypes and the adjacent breast parenchyma may form a pseudocapsule. The majority of myofibroblastomas are immunoreactive for CD34, desmin, smooth muscle actin, and vimentin and are negative for cytokeratin and S-100 protein. We present a case of a giant myofibroblastoma arising in the background of gynecomastia in an adult male.

Thyroid tumours with both papillary and medullary carcinoma features are rare and represent less than 1% of all thyroid malignancies. These tumours have a different clinical presentation and biological behaviour from tumours that have only papillary or medullary carcinoma features. The phenomenon of mixed thyroid tumours can be observed in two settings--a mixed tumour showing dual differentiation, or a collision tumour. For a precise diagnosis of this rare mixed thyroid carcinoma, fine needle aspiration cytology results should be correlated with serum calcitonin and thyroglobulin levels. The diagnosis should also be confirmed using immunocytochemistry. Surgery is the treatment of choice, and the role of postoperative radioiodine is controversial. We herein report the case of a 35-year-old man with a mixed medullary-papillary carcinoma of the thyroid, which presented with C-cell hyperplasia, granulomatous inflammation and metastasis to the cervical lymph nodes. The patient was treated with total thyroidectomy and nodal clearance. This case highlights the need for awareness of coexistent entities as they warrant separate treatments.

Purpose:
These days laparoscopic inguinal hernia surgery, both totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP), is a commonly performed procedure due to advancements in laparoscopic instruments and the availability of skilled laparoscopic surgeons. The purpose of this study was to compare the perioperative complications of these two procedures.
Methods:
This was a prospective observational study between July 2019 and December 2020. Perioperative complications were compared with a 6-month follow-up. It included 144patients, of whom 71 underwent TAPP repair and 73 underwent TEP repair. The selection wasbased on the surgeon’s choice.
Results:
Early postoperative complications were scrotal edema (12 cases in TEP and 16 in TAPP), urinary retention (one case in TEP), ecchymosis (six cases in TEP and two in TAPP), and scrotal subcutaneous emphysema (two cases in TEP). On follow-up, seroma was found in a total of 22 cases, of which 12 were TEP and 10 were TAPP. While only one case of TAPP developed surgical site infection. There was no statistically significant difference in hospital stay between the two groups (p = 0.58). The pain scores significantly decreased throughout recovery and were comparable between the groups. Neither group experienced a recurrence during the 6-month follow-up. Fifty-eight patients developed Clavien-Dindo grade I complications, one had grade II, and three had grade IIIa complications.
Conclusion
With the increasing experience of the surgical fraternity in laparoscopic surgery, TEP and TAPP were proven to be comparable in terms of duration of surgery, postoperative complications, hospital stay, pain scores, and recurrence during the 6-month follow-up.

Objectives:
This is a diagnostic test research study to evaluate the various existing methods of thyroid examination and their comparison with the novel modified Rose method. It also aims to measure inter-examiner variation in clinical findings based on the level of education and training, as compared to ultrasonography.
Methodology:
This cross-sectional study was conducted at a tertiary care hospital with 83 patients presenting to surgery OPD with neck swelling. Each patient was examined by one trained Junior Resident and a Surgery Consultant with all the four methods and with ultrasonography. Data was analysed by Stata-14, agreement between the two categorical variables was assessed by Kappa. In case of continuous variable agreement was assessed by Intra class correlation and Bland-Altman plot.
Results:
Modified Rose method by the consultant has the highest sensitivity (98%) and diagnostic odds (210) as compared to others but its specificity ranges from 46.7-91.1% to diagnose retro-sternal extension of a goiter. It has 93.98% agreement for identification of nodules. It has a high specificity (Consultant - 100%, Resident - 95.5%) with relatively lower sensitivity (Consultant - 94%, Resident - 86.8%) to diagnose solitary thyroid nodule (STN) but the sensitivity and specificity for diagnosing a multinodular goitre (MNG) was high. However, the highest sensitivity to diagnose STN was highest with Crile’s method, but specificity was low. Lahey’s method was a better clinical method to palpate lymph nodes compared to the other three.
Conclusion
Examination in modified Rose’s position is a better method of clinical examination of thyroid especially in patients with occult substernal extension. Lahey’s method is a better method to examine cervical lymph nodes.
